Forecast calls for nanoflowers to help return eyesight
2011-05-08
EUGENE, Ore. -- University of Oregon researcher Richard Taylor is on a quest to grow flowers that will help people who've lost their sight, such as those suffering from macular degeneration, to see again.
These flowers are not roses, tulips or columbines. They will be nanoflowers seeded from nano-sized particles of metals that grow, or self assemble, in a natural process -- diffusion limited aggregation. They will be fractals that mimic and communicate efficiently with neurons.
Fractals are "a trademark building block of nature," Taylor says. Fractals are objects with ...
DNA from common stomach bacteria minimizes effects of colitis, U-M study says
2011-05-08
ANN ARBOR, Mich. — DNA from Helicobacter pylori, a common stomach bacteria, minimizes the effects of colitis in mice, according to a new study by University of Michigan Medical School scientists.
The study published in Gut this month was performed by a team of investigators assembled by senior author John Y. Kao, M.D. of the University of Michigan's Division of Gastroenterology and assistant professor in U-M's Department of Internal Medicine. The findings indicate that DNA from H. pylori significantly ameliorates the severity of colitis, say lead authors Jay Luther, M.D. ...
When self-esteem is threatened, people pay with credit cards
2011-05-08
Los Angeles, CA - People shop for high status items when they're feeling low, and they're more likely to make those expensive purchases on credit, according to a study in the current Social Psychological and Personality Science (published by SAGE).
When a person's ego is threatened—by doing poorly on a task, by being told they're not as good as they hoped—people sometimes repair their self-worth by purchasing luxury goods. Because actually parting with cash can be psychologically painful, researchers Niro Sivanathan of the London Business School and Nathan Pettit of Cornell ...
No smoking policies may present challenges to treatment centers
2011-05-08
COLUMBUS, Ohio – When a new tobacco-free policy was instituted at an Ohio women's substance abuse treatment center, both smokers and non-smokers were more likely to leave treatment early in the first few months after the policy change, a new study found.
The results don't mean treatment centers shouldn't try smoking bans, according to the researchers, but they do highlight the challenges involved with implementing a new policy that goes against years of conventional thinking.
Researchers found that the number of patients who completed a program at the women's treatment ...
Study probes sources of Mississippi River phosphorus
2011-05-08
MADISON, WI MAY 5, 2011 – In their eagerness to cut nitrogen and phosphorus pollution in the Mississippi River and Gulf of Mexico, people have often sought simple explanations for the problem: too many large animal operations, for instance, or farmers who apply too much fertilizer, which then flows into waterways.
But according to new modeling research that examined phosphorus loading from all 1768 counties in the Mississippi River Basin (MRB), the true causes aren't nearly so straightforward. Livestock manure is widespread in many MRB counties, for example, but it shows ...
UT Southwestern research reveals how cancer-driving enzyme works
2011-05-08
DALLAS – May 6, 2011 – Cancer researchers at UT Southwestern Medical Center are helping unlock the cellular-level function of the telomerase enzyme, which is linked to the disease's growth.
Their latest findings, published today in Molecular Cell, demonstrate that telomerase repairs chromosomes in one of two ways – depending on whether a cell is dividing normally or if the cell is under stress from enzyme inhibition – and could lead to new or improved cancer-fighting therapies that promote inhibition of this enzyme.
"It's a significant advance in our understanding of ...
Vatican science panel calls attention to the threat of glacial melt
2011-05-08
A panel of some of the world's leading climate and glacier scientists co-chaired by a Scripps Institution of Oceanography, UC San Diego researcher issued a report today commissioned by the Vatican's Pontifical Academy of Sciences citing the moral imperative before society to properly address climate change.
The co-authors of "Fate of Mountain Glaciers in the Anthropocene" list numerous examples of glacial decline around the world and the evidence linking that decline to human-caused changes in climate and air pollution. The threat to the ways of life of people dependent ...
Spikemoss genome offers new paths for biofuels research -- bridges plant development gap
2011-05-08
WALNUT CREEK, Calif.— It's not quite Christmas, but the DNA sequence of a small plant that resembles the seasonal conifers is providing biofuels researchers with information that could influence the development of candidate biofuel feedstock plants and offering botanists long-awaited insights into plant evolution.
"When you burn coal, you're burning Selaginella's ancestors," said Purdue University botanist Jody Banks, who originally proposed that the U.S. Department of Energy (DOE) Joint Genome Institute (JGI) sequence the plant more commonly known as spikemoss as part ...

2011-05-08
San Diego, CA, May 5, 2011 – A study published in the June 2011 issue of the American Journal of Preventive Medicine examined the association between patient–physician gender concordance and weight-related counseling in obese individuals. Investigators from the University of Pennsylvania and Johns Hopkins University found that obese male patients seeing male physicians had higher odds of receiving weight-related counseling than obese women seeing a female physician.
Commenting on the study, Octavia Pickett-Blakely, MD, MHS, Hospital of the University of Pennsylvania, ...
Families are 'lovin' it'
2011-05-08
Philadelphia, PA, May 6, 2011 – According to the United States Department of Agriculture, Americans are spending about half their food budget in restaurants. As it is widely known, food prepared away from home, as compared to food prepared at home, is often higher in calories, saturated fat, and sodium. With children's dietary quality at risk, a study in the May/June 2011 issue of the Journal of Nutrition Education and Behavior explores the influence of parental styles and work schedules on children's use of and time spent in fast-food and full-service restaurants.

Tree rings tell a 1,100-year history of El Niño
2011-05-08
El Niño and its partner La Niña, the warm and cold phases in the eastern half of the tropical Pacific, play havoc with climate worldwide. Predicting El Niño events more than several months ahead is now routine, but predicting how it will change in a warming world has been hampered by the short instrumental record. An international team of climate scientists has now shown that annually resolved tree-ring records from North America, particularly from the US Southwest, give a continuous representation of the intensity of El Niño events over the past 1100 years and can be used ...
Oregon's Complicated Drug Delivery Laws

Oregon's Complicated Drug Delivery Laws
One of the most frequent complaints regarding Oregon State drug delivery charges is that the suspect never sold or delivered the drugs in question. "How can they charge me with delivery when I never sold anything?" The answer has to do with a tricky and dangerous quirk of Oregon's drug delivery laws.
Oregon law defines "delivery" as the "actual", "constructive", or "attempted" transfer of a controlled substance from one person to another. Problems arise for clients who are charged ...

Complying With Federal Safety Regulations Does Not Excuse Car Manufacturers
The United States Supreme Court recently issued an opinion that opens the door to personal injury and wrongful death lawsuits against car manufacturers under state law. The ruling against Mazda Motor of America came after the family of a woman killed in an motor vehicle accident involving a minivan sued Mazda in state court. The family claimed that Mazda was negligent in failing to install rear seat lap-and-shoulder seatbelts that could have prevented the woman's fatal injuries. Mazda argued ...
Insight into HIV immunity may lead to vaccine
2011-05-08
Latest insights into immunity to HIV could help to develop a vaccine to build antibodies' defences against the disease, a University of Melbourne, Australia study has found.
By investigating the action of the human antibodies called ADCC, in people with HIV, researchers were able to identify that the virus evolves to evade or 'escape' the antibodies.
Professor Stephen Kent of the University of Melbourne and one of the senior authors on the paper said ADCC antibodies have been strongly implicated in protection from HIV in several vaccine trials but their action was poorly ...
Chemistry curbs spreading of carbon dioxide
2011-05-08
The presence of even a simple chemical reaction can delay or prevent the spreading of stored carbon dioxide in underground aquifers, new research from the University of Cambridge has revealed.
The findings may have implications for carbon sequestration in saline aquifers – one of the many methods being explored to mitigate rising CO2 levels in the atmosphere.
Depending on the strength of the reaction between dissolved CO2 and porous rock, the new research shows that distinct scenarios of CO2 transport may occur in deep saline rock formations.

The Effect of Bankruptcy on Credit Scores
People who are mired in debt often dread the thought of filing for bankruptcy protection and the effect it will have on their credit scores. Many in this situation fear that they will never be able to obtain a loan, get a credit card or that they will be turned down for jobs, all because of a poor credit score.
As a matter of course, bankruptcy can have a serious effect on your credit score. It can lower your score by nearly 240 points. How much it will drop will depend on the type of debts you have and your prior credit history. ...
Computers sing to a better tune
2011-05-08
Music producers have for decades had electronics tricks at their disposal for improving a recorded vocal performance. They can add a little reverb or echo to bolster a weak rendition, use effects such as phasing and delay to add color to the vocal, fix duff notes with auto-tuning or even reprogram a whole melody line in software. In recent years, voice synthesis for converting text to spoken word has improved considerably but combining that technology with auto-tuning capability allows computers to "sing".
Software, such as Vocaloid, can successfully create lead vocals ...
Rice U. study: Daily deal promotions beneficial for certain kinds of startups
2011-05-08
In the first-of-its-kind analysis of Groupon's impact on a startup company, a new Rice University study found that the daily deal promotion was beneficial even though it had no material impact on the company's profits when unredeemed Groupons were not accounted for. When those unredeemed Groupons were factored in, the company had a substantial 30 percent increase in profits.
Having run the Groupon promotion, the company – Houston-based startup Gourmet Prep Meals (GPM) – had greater exposure and earned revenues almost 140 percent higher than it would have earned had it ...

Florida Legislature Looks at Better Criminal Identification Procedures
TV crime programs tend to suggest that every aspect of solving a crime lends itself to forensic science, as if CSI has been reduced to a magical formula. But in many criminal investigations, identification of the alleged perpetrator is still dependent on the recollections of eyewitnesses. And all too often, a false identification can lead to a prosecution of the wrong suspect in a homicide, sexual assault or theft case, all due to a convergence of unfortunate circumstances.

From a bucket of seawater, new understanding of the ocean
2011-05-08
NEW BRUNSWICK, N.J. – From a bucket of seawater, scientists have unlocked information that may lead to deeper understanding of organisms as different as coral reefs and human disease. By analyzing genomes of a tiny, single-celled marine animal, they have demonstrated a possible way to address diverse questions such as how diseased cells differ from neighboring healthy cells and what it is about some Antarctic algae that allows them to live in warming waters while other algae die out.

Mars Express sees deep fractures on Mars
2011-05-08
Newly released images from ESA's Mars Express show Nili Fossae, a system of deep fractures around the giant Isidis impact basin. Some of these incisions into the martian crust are up to 500 m deep and probably formed at the same time as the basin.
Nili Fossae is a 'graben' system on Mars, northeast of the Syrtis Major volcanic province, on the northwestern edge of the giant Isidis impact basin. Graben refers to the lowered terrain between two parallel faults or fractures in the rocks that collapses when tectonic forces pull the area apart. The Nili Fossae system contains ...

Bard Avaulta Surgical Mesh Lawsuits
Implantable medical devices from artificial hips to heart values have made it possible for people to have healthier, longer and more productive lives. There can be a dark side to these devices, however, as sometimes they are more harmful than helpful.
For example, in October 2008, the FDA issued a warning regarding the potential danger of surgical meshes after receiving more than 1,000 adverse-event reports. Since the FDA warning, a number of women have filed product liability lawsuits against C.R. Bard, Inc. and other mesh manufacturers ...
Leading experts call for urgent action to avoid stroke crisis across Asia-Pacific region
2011-05-08
Experts from medical and patient communities call on national policymakers in the Asia-Pacific region to take urgent action against preventable strokes that strike millions of people with atrial fibrillation (AF) each year
Countries in the Asia-Pacific region carry a disproportionate share of the burden of stroke with millions of people affected; a burden that will grow as life expectancy rises1
AF, the most common, sustained abnormal heart rhythm, increases the risk of stroke five-fold and is responsible for 15-20% of all strokes, and for 20% of all ischaemic strokes ...
